# Neural Pipeline
Neural networks training pipeline based on PyTorch. Designed to standardize training process and accelerate experiments.

* Core is about 2K lines, covered by tests, that you don't need to write again
* Flexible and customizable training process
* Checkpoints management and train process resuming (source and target device independent)
* Metrics processing and visualization by builtin ([tensorboard](https://www.tensorflow.org/guide/summaries_and_tensorboard), [Matplotlib](https://matplotlib.org)) or custom monitors
* Training best practices (e.g. learning rate decaying and hard negative mining)
* Metrics logging and comparison (DVC compatible)

### Neural Pipeline short overview:
```python
import torch
from neural_pipeline.builtin.monitors.tensorboard import TensorboardMonitor
from neural_pipeline.monitoring import LogMonitor
from neural_pipeline import DataProducer, TrainConfig, TrainStage,\
ValidationStage, Trainer, FileStructManager
from somethig import MyNet, MyDataset
fsm = FileStructManager(base_dir='data', is_continue=False)
model = MyNet().cuda()
train_dataset = DataProducer([MyDataset()], batch_size=4, num_workers=2)
validation_dataset = DataProducer([MyDataset()], batch_size=4, num_workers=2)
train_config = TrainConfig(model, [TrainStage(train_dataset),
ValidationStage(validation_dataset)], torch.nn.NLLLoss(),
torch.optim.SGD(model.parameters(), lr=1e-4, momentum=0.5))
trainer = Trainer(train_config, fsm, torch.device('cuda:0')).set_epoch_num(50)
trainer.monitor_hub.add_monitor(TensorboardMonitor(fsm, is_continue=False))\
.add_monitor(LogMonitor(fsm))
trainer.train()
```
This example of training MyNet on MyDataset with vizualisation in Tensorflow and with metrics logging for further experiments comparison.
